50  * Juli does not use the standard ICE1724 clock scheme. Juli's ice1724 chip is
51  * supplied by external clock provided by Xilinx array and MK73-1 PLL frequency
52  * multiplier. Actual frequency is set by ice1724 GPIOs hooked to the Xilinx.
53  *
54  * The clock circuitry is supplied by the two ice1724 crystals. This
55  * arrangement allows to generate independent clock signal for AK4114's input
56  * rate detection circuit. As a result, Juli, unlike most other
57  * ice1724+ak4114-based cards, detects spdif input rate correctly.
58  * This fact is applied in the driver, allowing to modify PCM stream rate
59  * parameter according to the actual input rate.
60  *
61  * Juli uses the remaining three stereo-channels of its DAC to optionally
62  * monitor analog input, digital input, and digital output. The corresponding
63  * I2S signals are routed by Xilinx, controlled by GPIOs.
64  *
65  * The master mute is implemented using output muting transistors (GPIO) in
66  * combination with smuting the DAC.
67  *
68  * The card itself has no HW master volume control, implemented using the
69  * vmaster control.
